1.0 Introduction

The model RLC - 2013 footage counter is an instrument designed tomeasure the length of tissue paper rolls . It will accommodate standard 4 inchwide tissue rolls or 11 inch paper towel rolls having a 1 ½ inch core. In additionthe instrument will accept jumbo tissue rolls up to 15 inch diameter when usingthe optional jumbo roll adaptors. The machine consists of a top roller which includes a sensor thatmeasures the speed and length of the test sample. A front drive roll is providedthat is driven directly from a variable speed motor. This front drive roll has aface width of 9 inches and will either wind up the paper onto the windupspindle or simply feed the paper into a recycle bin. See the photos below thatillustrate these features. The drive motor features controls that allow for automatic operation. Theoperator simply threads the paper through the rollers and presses the startbutton. The motor will now run at a preset speed (variable) while the digitalmeter displays the footage being fed through the system. When the roll expiresthe instrument will automatically shut off and the total footage will remain onthe display. The footage counter will reset to 0.0 at the beginning of the nexttest. Ths machine is designed to be used both in the laboratory or directly onthe production floor. All of the electronic controls are housed in an industrialcabinet.

2.2 Resume Button Starts the test without resetting the counters. Used to restart a test.

2.3 Length Display Indicates the length of the roll.

2.4 Sheet Length Touching this display will generate a virtual key pad allowing the operatorto enter the length of a single sheet.

2.5 Sheet Count Indicates the number of sheets. This is the length measurement dividedby the length of the sheet.

3.0 Calibration Screen

3.1 Password Upon pressing the Calibrate button from the main screen the operator willsee a virtual keypad requesting a password. The password is “1 2 3 4" . Oncethe password is entered the above Calibration screen will appear. 3.2 Speed A factor installed multiplication factor is built into the software to achievethe proper speed reading on the main display when the calibration factor onthis display reads 1.000. If the speed reading on the main display is in error,one can adjust the Calibration factor here to adjust. Touching the Speeddisplay will activate a virtual keyboard. Enter a number smaller then 1.000 willyield a lower speed value.

3.3 Length A factor installed multiplication factor is built into the software to achievethe proper length reading on the main display when the calibration factor onthis display reads 1.000. If the length reading on the main display is in error,one can adjust the Calibration factor here to adjust. Touching the lengthdisplay will activate a virtual keyboard. Enter a number smaller then 1.000 willyield a lower speed value.

3.4 Leader Length This feature allows the instrument to compensate for the “leading” materialthat is used at the beginning of the test . Upon treading up the web simplymeasure the amount of leading material needed to start the wide up. You wantto make this measurement from the end of the web back to the end of sheetsensor. Enter this leader length by touching the Leader display on this screenand entering the length into the virtual keypad.

IMPORTANT NOTE ABOUT CALIBRATION It is important that the calibration be checked and adjusted with the actualproduct that you wish to test. The stretch of the paper and the stretch of theperforations (if the product is perforated) may affect the results. It isrecommended that a full roll of the desired product with a known length be runon this tester before it is put into use. Now the calibration should be checkedand adjusted if needed to allow for these factors.

6.0 Operation

6.1 Loading a Standard Roll Slide the roll onto the 1 ½ inch spindle as shown in figure 6. Secure the shaftcollar close to the roll core to act as an edge guide during the test.

Figure 6: Standard Roll

6.2 Loading a Jumbo Roll Slide the jumbo roll onto the 1 ½ inch spindle using the jumbo roll adaptors(optional) as shown in figure 7. The jumbo roll adaptors convert the 1 ½ inchdiameter spindle to 3 inches to accommodate these larger rolls.

6.3 Paper feed Raise the rewind spindle and set it on the lifter block as shown in figure 8.

Figure 8: Lifter Block Handle

Unwind about 18 inches of tissue and wrap it around the idler roller (abouta 90° wrap) and then pass it around the top roller (about a 180° wrap), over the“end of sheet detector” and lay it over the front drive roller as shown in Figure 1.Now lower the rewind spindle onto the front drive roller using the lifter blockhandle as shown in Figure 4. Now you will choose to rewind the paper onto the rewind spindle (see Figure9) or to feed it into the recycle bin (see Figure 10).

Figure 9: Rewind the Paper Sample

Figure 10: fed sample into recycle bin

Please note that there is a limit to how large the rewound rolls can be. Wehave found that the large “Hard Roll Towels” and the jumbo tissue rolls are toolarge to wind on a single roll. For these larger rollers simply press the stop buttonwhen the rewound roller gets about 6 - 8 inches in diameter, allow the machineto come to a stop. Tear the sample at the front drive roller. Remove the rewoundroll, install a new cardboard core and attach the free end. Now press the“resume” button and the tester will continue the test without resetting the “length”value. Please note that a cardboard core should be placed on the rewind spindleto act as a “nip” on the front drive roller as shown in Figure 6. When you startthe test, watch the end of the tissue sample to insure it feeds into the recycle binlocated at floor level in front of the machine.

6.4 Running a test Press the start button to start the motor and reset the length meter to 0.0.The instrument will now unwind the entire roller while displaying the length as itfeeds. When the end of the tissue passes the “end of sheet” detector the motorwill stop turning and the length of this test will remain on the digital display.
